Though the components of an extension pole vary by use, extension poles do have a basic internal structure common in all models. This internal system consists of a spring that allows the two sections of the extension pole to separate and compress. The spring inside a floor to ceiling extension pole forces sections of the pole apart to keep the unit securely in place between two surfaces.
Floor to ceiling extension poles made for support during a construction process don’t contain any extra components. Large, flat metal pieces sit at the top and bottom of a construction extension pole. Screw holes on the top and bottom pieces provide a means of attaching the pole to both the ceiling and floor. The interior has the basic internal spring system and a locking mechanism that locks the pole at a given height when twisted.
Some extension poles are designed for use as exercise or dance poles. Since these poles must hold up against a lot of tugging and movement, the floor to ceiling extension poles always have top and bottom plates with pre-drilled holes for screwing the pole to the wall and ceiling. To stretch the pole between the floor and ceiling, you generally extend the smaller end of the pole from the larger end and lock it into place by sliding the plastic or rubber ring on the pole.
Accessibility poles install near furniture or fixtures, such as chairs or toilets, built for the elderly or handicapped to provide support so that these people can live more independently. Components of accessibility poles may include jutting handholds, trays and clips to hold papers and other items, which vary by manufacturer.
